Description

Die Erfindung betrifft einen Abgasturbolader, der eine Regeleinheit zur Leistungsteuerung des Abgasturboladers und einen Aktuator aufweist, wobei die Regeleinheit von dem Aktuator verstellbar ist. Der Aktuator ist über eine Schubstange und ein Anschlusselement mit der Regeleinheit verbunden.The invention relates to an exhaust gas turbocharger having a control unit for power control of the exhaust gas turbocharger and an actuator, wherein the control unit is adjustable by the actuator. The actuator is connected via a push rod and a connection element with the control unit.

Abgasturbolader dienen dazu, den Wirkungsgrad eines Verbrennungsmotors zu verbessern und damit dessen Leistung zu steigern. Der Abgasturbolader weist hierzu eine Turbine mit einem Turbinenrad und einen Verdichter mit einem Verdichterrad auf, wobei die beiden Laufräder auf einer gemeinsamen Welle angeordnet sind. Das Turbinenrad wird hierbei über einen Abgasmassenstrom des Verbrennungsmotors angetrieben und treibt wiederum das Verdichterrad an. Der Verdichter verdichtet angesaugte Frischluft und führt diese dem Verbrennungsmotor zu. Die gemeinsame Welle ist in einem Lagergehäuse des Turboladers gelagert. Des Weiteren ist das Turbinenrad der Turbine in einem Turbinengehäuse angeordnet und das Verdichterrad des Verdichters in einem Verdichtergehäuse.Exhaust gas turbochargers serve to improve the efficiency of an internal combustion engine and thus to increase its performance. For this purpose, the exhaust gas turbocharger has a turbine with a turbine wheel and a compressor with a compressor wheel, wherein the two wheels are arranged on a common shaft. The turbine wheel is driven by an exhaust gas mass flow of the internal combustion engine and in turn drives the compressor wheel. The compressor compresses sucked fresh air and supplies it to the combustion engine. The common shaft is mounted in a bearing housing of the turbocharger. Furthermore, the turbine wheel of the turbine is arranged in a turbine housing and the compressor wheel of the compressor in a compressor housing.

Je mehr die Motordrehzahl steigt, desto schneller dreht sich durch die antreibende Abgasmenge das Turbinenrad der Turbine und mit diesem auch die Welle des Abgasturboladers, auf welcher sich weiterhin das Verdichterrad des Verdichters befindet. Durch die schnellere Drehung der Welle und damit auch des Verdichterrades erhöht sich die Luftfördermenge des Verdichters. Dies führt zu einer wachsenden Abgasmenge des Motors und damit wiederum zu einem schnelleren Antreiben des Turbinenrades. Um die jeweils gegebenen mechanischen und thermischen Grenzen des Motors nicht zu überschreiten, ist eine Regelung des Abgasturboladers notwendig.The more the engine speed increases, the faster the turbine wheel of the turbine rotates due to the driving exhaust gas quantity, and with this also the shaft of the exhaust gas turbocharger, on which the compressor wheel of the compressor remains. The faster rotation of the shaft and thus also of the compressor wheel increases the air flow rate of the compressor. This leads to a growing amount of exhaust gas of the engine and thus in turn to a faster driving of the turbine wheel. In order not to exceed the respective given mechanical and thermal limits of the engine, a regulation of the exhaust gas turbocharger is necessary.

Eine derartige Regelung eines Abgasturboladers kann unter Verwendung einer variablen Turbinengeometrie oder eines im Turbinengehäuse vorgesehenen Wastegatekanals bzw. Bypasskanals, der mittels eines Wastegate- oder Bypassventil genannten Schließelements verschließbar ist, erfolgen. Dieses Schließelement kann bei Bedarf geöffnet werden, um in Abhängigkeit von der Öffnungsstellung einen mehr oder weniger großen Teil des Abgases an der Turbine vorbei direkt in den Auspuff des Fahrzeugs zu leiten. Dadurch wird ein weiteres Ansteigen der Turbinendrehzahl unterbunden.Such a regulation of an exhaust-gas turbocharger can take place using a variable turbine geometry or a wastegate channel or bypass channel provided in the turbine housing, which can be closed by means of a closing element called a wastegate or by-pass valve. This closing element can be opened as needed to guide a more or less large part of the exhaust gas past the turbine directly into the exhaust of the vehicle depending on the open position. As a result, a further increase in the turbine speed is prevented.

Es ist bekannt, eine solche Regeleinheit (Schließelement eines Wastegatekanals oder variable Turbinengeometrie) unter Verwendung eines elektrischen oder pneumatischen Aktuators zu verstellen.It is known to adjust such a control unit (closing element of a wastegate channel or variable turbine geometry) using an electric or pneumatic actuator.

Es ist des Weiteren bereits bekannt, die Kopplung eines derartigen Aktuators mit der Regeleinheit unter Verwendung eines aktuatorseitigen Stellglieds, zum Beispiel einer Schubstange oder Regelstange, und eines schließelementseitigen Betätigungshebels vorzunehmen.Furthermore, it is already known to carry out the coupling of such an actuator to the control unit using an actuator-side actuator, for example a push rod or control rod, and a closing element-side actuating lever.

Um eine exakte Steuerung der Regeleinheit mittels des Aktuators zu gewährleisten, ist es notwendig, Fertigungs- und Montagetoleranzen der einzelnen Komponenten und deren Position zueinander auszugleichen. Daher muss jeder Abgasturbolader genau abgestimmt werden, was einen erheblichen Justier- und Montageaufwand bei der Montage erforderlich macht.In order to ensure exact control of the control unit by means of the actuator, it is necessary to compensate for manufacturing and assembly tolerances of the individual components and their position to each other. Therefore, each exhaust gas turbocharger must be tuned exactly, which makes a considerable adjustment and assembly effort required during assembly.

Aus der DE 10 2011 007072 A1 ist ein Abgasturbolader bekannt, der einen mittels eines Schließelementes verschließbaren Wastegatekanal aufweist. Der das Schließelement verstellbare Aktuator ist mit dem Schließelement über ein als Regelstange ausgebildetes Stellglied und ein zwischen dem Stellglied und dem Schließelement vorgesehenes schwenkbares Führungselement als Betätigungshebel verbunden. Das Führungselement ist mit einem flach ausgebildeten Führungshebel verbunden, der in einen Schlitz des Stellglieds eingesetzt ist.From the DE 10 2011 007072 A1 an exhaust gas turbocharger is known which has a closable by means of a closing element wastegate channel. The actuator which adjusts the closing element is connected to the closing element via an actuator designed as a control rod and a pivotable guide element provided between the actuating element and the closing element as an actuating lever. The guide element is with a flat formed guide lever which is inserted into a slot of the actuator.

In der EP 1256703 B1 ist ebenfalls ein Abgasturbolader offenbart, der einen Wastegatekanal, ein Schließelement und einen Aktuator aufweist. Das Schließelement kann über einen Betätigungshebel geöffnet oder geschlossen werden, wobei das Stellglied, eine Regelstange des Aktuators, mit dem Betätigungshebel verbunden ist. Sie umfasst ein längliches Element und wenigstens ein Abschnitt dieses Elements ist ausreichend flexibel, um sich bei der Verwendung um eine Linie zu biegen, um so Positionsabweichungen zu kompensieren.In the EP 1256703 B1 Also disclosed is an exhaust gas turbocharger having a wastegate channel, a closure member and an actuator. The closing element can be opened or closed via an actuating lever, wherein the actuator, a control rod of the actuator, is connected to the actuating lever. It comprises an elongated member and at least a portion of this member is sufficiently flexible to bend in use around a line so as to compensate for positional deviations.

Ferner zeigt die JP S59 153920 A einen Abgasturbolader mit einem Wastegateventil, wobei das Ventil mittels eines Aktuators mehr oder weniger weit geöffnet werden kann.Furthermore, the shows JP S59 153920 A an exhaust gas turbocharger with a wastegate valve, wherein the valve can be opened more or less wide by means of an actuator.

Weiterhin wird auf die US 2004 0028 468 A1 hingewiesen, die eine einstellbare Schubstange offenbart, die eine Einstellhülse aufweist, wobei die Schubstange zur Einstellung ihrer Länge durch Drehung der Einstellhülse verlängert oder verkürzt werden kann.Furthermore, on the US 2004 0028 468 A1 noted that discloses an adjustable push rod having an adjusting sleeve, wherein the push rod can be extended or shortened to adjust its length by rotation of the adjusting sleeve.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen Abgasturbolader mit einer Regeleinheit, die mittels eines Aktuators über einen Betätigungshebel und eine Schubstange verstellt wird, zu entwickeln, wobei in einer Verbindung zwischen dem Betätigungshebel und der Schubstange auftretende Fertigungs- und Montagetoleranzen ausgeglichen werden, wobei die Verbindung möglichst einfach herzustellen ist, und wobei eine möglichst einfache Zugänglichkeit dieser Verbindung für die Montage ermöglicht wird.The present invention has for its object to develop an exhaust gas turbocharger with a control unit, which is adjusted by means of an actuator via an actuating lever and a push rod, wherein occurring in a connection between the actuating lever and the push rod manufacturing and assembly tolerances are compensated, the Connection is as simple as possible to produce, and wherein the simplest accessibility of this compound for mounting is possible.

Diese Aufgabe wird erfindungsgemäß durch einen Abgasturbolader mit den Merkmalen des Hauptanspruchs gelöst. Vorteilhafte Ausgestaltungen der Erfindung ergeben sich mit den Merkmalen der Unteransprüche.This object is achieved by an exhaust gas turbocharger with the features of the main claim. Advantageous embodiments of the invention will become apparent with the features of the subclaims.

Der vorgeschlagene Abgasturbolader weist eine Regeleinheit zur Leistungsregelung des Abgasturboladers und einen Aktuator zur Betätigung der Regeleinheit auf. Die Regeleinheit ist über einen ihr zugeordneten Betätigungshebel mittels einer Schubstange des Aktuators betätigbar und die Schubstange des Aktuators ist mit einem Betätigungshebel der Regeleinheit über ein Einstellglied verbunden. Das Einstellglied weist ein Schrauben-Mutterelement und ein damit in Eingiff stehendes Anschlusselement auf, wobei das Anschlusselement mit dem Betätigungshebel gekoppelt ist und das Schrauben-Mutterelement einen ersten Gewindebereich aufweist, über den es mit dem Anschlusselement gekoppelt ist und einen zweiten Gewindebereich, über den es mit der Schubstange gekoppelt ist. Erfindungsgemäß ist der Abgasturbolader dadurch gekennzeichnet, dass das Schrauben-Mutterelement ein in einer Durgangsbohrung angeordnetes Innengewinde und ein auf dem Außenumfang eines zylinderförmigen Ansatzstückes angeordnetes Außengewinde aufweist, wobei das Anschlusselement ein dem Außengewinde (5) des Schrauben-Mutterelementes (1) entsprechendes Innengewinde und die Schubstange dazu korrespondierend ein dem Innengewinde (4) des Schrauben-Mutterelementes (1) entsprechendes Außengewinde aufweist, die jeweils mit dem Schrauben-Mutterelement verschraubt sind.The proposed exhaust gas turbocharger has a control unit for power control of the exhaust gas turbocharger and an actuator for actuating the control unit. The control unit can be actuated via an associated actuating lever by means of a push rod of the actuator and the push rod of the actuator is connected to an actuating lever of the control unit via an adjusting member. The adjusting member has a nut and a threaded engagement therewith, wherein the connecting element is coupled to the actuating lever and the screw-nut element has a first threaded portion, via which it is coupled to the connecting element and a second threaded portion over which it coupled with the push rod. According to the exhaust gas turbocharger is characterized in that the screw nut element has a arranged in a Durgangsbohrung internal thread and arranged on the outer circumference of a cylindrical extension piece external thread, said connecting element a the external thread (5) of the screw nut element (1) corresponding internal thread and the Push rod corresponding thereto has an internal thread (4) of the screw-nut element (1) corresponding external thread, which are each bolted to the screw nut element.

Erfindungsgemäß weist das Schrauben-Mutterelement in der Durchgangsbohrung ein Innengewinde und auf dem Außenumfang des zylinderförmigen Ansatzstückes ein Außengewinde auf. Bei dieser Ausführung weist dann das Anschlusselement ein dem Außengewinde des Ansatzstückes entsprechendes Innengewinde auf und die Schubstange des Aktuators weist auf ihrem Außenumfang ein dem Innengewinde der Durchgangsbohrung des Schrauben-Mutterelements entsprechendes Außengewinde auf. Die Schubstange des Aktuators ist dann in der Durchgangsbohrung des Schrauben-Mutterelements angeordnet und steht im Eingriff mit dessen Innengewinde. Das zylinderförmige Ansatzstück des Schrauben-Mutterelements wiederum steht mit seinem Außengewinde im Eingriff mit dem Innengewinde des Anschlusselements.According to the invention, the screw-nut element has an internal thread in the through-bore and an external thread on the outer circumference of the cylindrical extension piece. In this embodiment, then, the connection element has an internal thread corresponding to the external thread of the attachment piece, and the push rod of the actuator has on its outer circumference a male thread corresponding to the internal thread of the through-hole of the screw-nut element. The push rod of the actuator is then arranged in the through hole of the screw nut member and is engaged with its internal thread. The cylindrical extension of the screw-nut element in turn is with its external thread in engagement with the internal thread of the connecting element.

Weiterhin weisen das Innengewinde in der Durchgangsbohrung und das Außengewinde auf dem Ansatzstück des Schrauben-Mutterelementes jeweils ein gleichsinnig verlaufendes Gewinde mit gleicher Steigung auf.Furthermore, the internal thread in the through hole and the external thread on the end piece of the screw-nut element each have a co-extending thread with the same pitch.

Die Montage des Anschlusselements und der Schubstange kann dann in einfacher Weise in einem Schraubvorgang mittels des Schrauben-Mutterelements erfolgen.
Durch die Schraubverbindung zwischen Schrauben-Mutterelement und Anschlusselement des Einstellgliedes können Fertigungs- und Montagetoleranzen, die den Abstand zwischen Aktuator und Regeleinheit betreffen, auf einfache Art ausgeglichen werden und eine Verbindung zwischen der Schubstange des Aktuators und dem Betätigungshebel kann in der Montage auf einfache Weise positionsgenau eingestellt werden. Darüber hinaus erlaubt die Verwendung dieses Einstellgliedes es, die Schubstange des Aktuators von lediglich einer Seite aus mit dem Betätigungshebel zu befestigen. Hierdurch wird eine herkömmliche Verbindungstechnik zum Beispiel mittels zweier justierbarer Konter-Muttern vorteilhaft ersetzt, welche eine beidseitige, schwer zu automatisierende Zugänglichkeit am Anschlusselement erfordert. Durch eine Automatisierung wird eine Montage der Verbindung zwischen der Schubstange und dem Anschlusselement vereinfacht und es können Kosten eingespart werden.The assembly of the connecting element and the push rod can then be done in a simple manner in a screwing by means of the screw-nut element.
Due to the screw connection between the screw-nut element and connection element of the adjusting manufacturing and assembly tolerances that affect the distance between the actuator and control unit can be compensated in a simple way and a connection between the push rod of the actuator and the operating lever can be accurately positioned in the assembly in a simple manner be set. In addition, the use of this adjustment allows it to attach the push rod of the actuator from only one side with the operating lever. As a result, a conventional connection technology is advantageously replaced, for example by means of two adjustable counter-nuts, which requires a double-sided, difficult to automate accessibility on the connection element. Through automation, an assembly of the connection between the push rod and the connection element is simplified and costs can be saved.

Diese Ausführung ist besonders vorteilhaft wenn beim Montagevorgang, beim Erstellen der Verbindung zwischen Schrauben-Mutterelement und Anschlusselement die voreingestellte Position von Schubstange und Betätigungshebel beibehalten, also nicht mehr verändert werden sollen. Dies ist insbesondere von Vorteil, wenn es sich bei dem Aktuator um einen elektromechanischen Aktuator handelt.This design is particularly advantageous when the assembly process, when creating the connection between the screw-nut element and connection element, the preset position of push rod and operating lever maintained, so should not be changed. This is particularly advantageous if the actuator is an electromechanical actuator.

Gleichfalls kann jedoch ein pneumatischer Aktuator eingesetzt werden. Auch in diesem Fall wird bei der Montage zunächst das Schrauben-Mutterelement auf das Außengewinde der Schubstange aufgedreht und das Anschlusselement mit dem Betätigungshebel der Regeleinheit verbunden. Dann werden die Schubstange mit dem Schrauben-Mutterelement sowie der Betätigungshebel mit dem Anschlusselement in die gewünschte Position zueinander gebracht. In weiterer Folge wird dann das Schrauben-Mutterelement entgegen der Drehrichtung beim Aufdrehen auf die Schubstange gedreht, wobei das Außengewinde des Ansatzstückes in Eingriff mit dem Innengewinde des Anschlusselements gebracht wird. Durch die Gleichsinnigkeit und die gleiche Steigung der Gewinde bewegt sich nun das Schrauben-Mutterelement in gleichem Maß und gleicher Richtung relativ zu Schubstange und Anschlusselement in das Innengewinde des Anschlusselements hinein und stellt so die Verbindung her.Likewise, however, a pneumatic actuator can be used. Also in this case, the first screw-nut element on the external thread of the Turned push rod and the connection element connected to the operating lever of the control unit. Then, the push rod with the screw nut element and the actuating lever with the connection element are brought into the desired position to each other. Subsequently, the screw-nut element is then rotated counter to the direction of rotation when screwing on the push rod, wherein the external thread of the extension piece is brought into engagement with the internal thread of the connection element. Due to the sense of coherence and the same pitch of the thread now moves the screw-nut element in the same degree and the same direction relative to push rod and connecting element in the internal thread of the connecting element and thus establishes the connection.

In einer alternativen Ausführungsform können das Innengewinde in der Durchgangsbohrung und das Außengewinde auf dem Ansatzstück des Schrauben-Mutterelementes, sowie die zugehörigen Außengewinde auf der Schubstange bzw. Innengewinde im Anschlusselement auch gleichsinnig verlaufen jedoch jeweils eine unterschiedliche Steigung aufweisen.
Wenn nun mittels des Einstellglieds mit dem Betätigungshebel verbunden wird, wie oben beschrieben, dann werden sich durch die unterschiedlichen Steigungen der Gewinde die Schubstange und das Anschlusselement zusammen mit dem Betätigungshebel relativ zu einander verschieben. Diese Ausführung ist vor allem von Vorteil wenn der Aktuator ein pneumatischer Aktuator ist. Dann kann nämlich die genannte relative Verschiebung durch eine elastische Ruckstellung einer sich im Aktuator befindenden Feder kompensiert werden. Die Feder kann somit bei der Montage des Systems vorgespannt werden.In an alternative embodiment, the internal thread in the through hole and the external thread on the end piece of the screw nut element, and the associated external thread on the push rod or internal thread in the connection element can also extend in the same direction, however, each having a different pitch.
Now, if by means of the adjusting member is connected to the actuating lever, as described above, then the push rod and the connecting element will move together with the actuating lever relative to each other by the different pitches of the thread. This embodiment is particularly advantageous if the actuator is a pneumatic actuator. Then namely, said relative displacement can be compensated by an elastic return of a spring located in the actuator. The spring can thus be biased during assembly of the system.

In einer bevorzugten Ausführungsform umfasst das Schrauben-Mutterelement einen für das Aufsetzen eines Festziehwerkzeuges, zum Beispiel einen Schraubenschlüssel, ausgebildeten, auch als Kopf bezeichneten Betätigungsbereich, der vorzugsweise als Sechskant-Schraubenkopf ausgebildet ist, und welcher mit dem zylinderförmigen, eine Durchgangsbohrung aufweisenden Ansatzstück des Schrauben-Mutterelements einstückig verbunden ist. Mittels des Festziehwerkzeuges können das Schrauben-Mutterelement und das Anschlusselement in der Montage dann durch ineinanderschrauben auf einfache Weise miteinander verbunden werden. Dadurch, dass dazu nur das Schrauben-Mutterelement betätigt werden muss, ist in der Montage lediglich der Zugang zum Kopf des Schrauben-Mutterelements und der Einsatz eines Werkzeugs erforderlich.In a preferred embodiment, the screw-nut element comprises a for actuating a tightening tool, for example a wrench, formed, also referred to as a head operating portion, which is preferably designed as a hex screw head, and which with the cylindrical, a through hole having connecting piece of the screw-nut element is integrally connected. By means of the tightening tool, the screw-nut element and the connecting element in the assembly can then be connected to one another in a simple manner by nested screws. Due to the fact that only the screw nut element has to be actuated for this purpose, only the access to the head of the screw nut element and the use of a tool are required in the assembly.

Um einem eventuellen Verschleiß im Schrauben-Mutterelement vorzubeugen, kann es vorteilhaft sein, das Schrauben-Mutterelement nach dem Verbinden der Schubstange mit dem Anschlusselement mit einer Kontermutter zu verspannen. Ein Verdrehen des Schrauben-Mutterelements während des Betriebs des Turboladers wird hierdurch verhindert. Hierzu kann die Kontermutter beispielsweise auf der Schubstange vormontiert sein.In order to prevent any wear in the screw-nut element, it may be advantageous to brace the screw-nut element after connecting the push rod with the connecting element with a lock nut. A rotation of the screw-nut element during operation of the turbocharger is thereby prevented. For this purpose, the lock nut can be preassembled for example on the push rod.

In den hier gezeigten Ausführungsbeispielen besteht die Regeleinheit aus einem Wastegatekanal mit einem Schließelement. Eine Regelung des Drucks in dem Verdichtergehäuse kann aber auch durch eine variable Turbinengeometrie erfolgen. Dabei erfolgt eine Verstellung der Turbinengeometrie ebenso über eine Betätigung eines Aktuators.In the embodiments shown here, the control unit consists of a wastegate channel with a closing element. A regulation of the pressure in the compressor housing but can also be done by a variable turbine geometry. In this case, an adjustment of the turbine geometry also takes place via an actuation of an actuator.

Die Figur 1 zeigt eine bei dem erfindungsgemäßen Abgasturbolader 20 verwendete Verbindung zwischen einer Schubstange 9 und einem Anschlusselement 6 mittels eines Schrauben-Mutterelementes 1. Die Schubstange 9 ist mit einem an dem Verdichtergehäuse des Abgasturboladers befestigten Aktuator 21 fest verbunden, während das Anschlusselement 6 über eine Gelenkverbindung an einem Bypassventil, das als Schließelement dient, eines sich im Turbinengehäuse 22 befindenden Wastegatekanals angeschlossen ist. Die Gelenkverbindung wird durch mindestens einen Hebel gebildet, der gelenkig an einem am Anschlusselement 6 angeordneten Ansatz 12 angelenkt ist. Der Aktuator 21 kann abhängig vom Druck im Verdichtergehäuse über die genannte Verbindung das Bypassventil mehr oder wenig weit öffnen bzw. schließen, um somit die Turbinenleistung zu regeln. Um in einer Kopplung zwischen dem Bypassventil und dem Aktuator 21 auftretende Fertigungs- und Montagetoleranzen auszugleichen, ist die Verbindung zwischen der Schubstange 9 und dem Anschlusselement 6 über das Schrauben-Mutterelement 1 ausgebildet.The FIG. 1 shows a connection used in the exhaust gas turbocharger 20 according to the invention between a push rod 9 and a connecting element 6 by means of a screw-nut element 1. The push rod 9 is fixedly connected to an attached to the compressor housing of the exhaust gas turbocharger actuator 21, while the connecting element 6 via a hinge connection on a Bypass valve, which serves as a closing element, a located in the turbine housing 22 Wastegatekanals is connected. The articulated connection is formed by at least one lever, which is hingedly articulated to a connection 12 arranged on the connecting piece 6. Depending on the pressure in the compressor housing, the actuator 21 can more or less open or close the bypass valve via the named connection in order thus to regulate the turbine output. In order to compensate for manufacturing and assembly tolerances occurring in a coupling between the bypass valve and the actuator 21, the connection between the push rod 9 and the connection element 6 is formed via the screw nut element 1.

Die Figur 2 zeigt eine schematische Skizze des Schrauben-Mutterelements 1, das einen für das Aufsetzen eines Festziehwerkzeuges ausgebildeten Schraubenkopf 2 in Sechskantform aufweist, der mit einem zylinderförmigen, eine Bohrung aufweisenden Ansatzstück 3 einstückig verbunden ist. Die Bohrung ist mit einem Innengewinde 4 versehen und an dem zylinderförmigen Außenumfang des Ansatzstückes 3 ist ein Außengewinde 5 angebracht. Die das Innengewinde 4 aufweisende Bohrung durchgreift den Schraubenkopf 2. Das Schrauben-Mutterelement 1 ist zwecks einer möglichst einfachen Montage auf der Schubstange 9 vormontierbar.The FIG. 2 shows a schematic sketch of the screw-nut element 1, which has a trained for the placement of a tightening tool screw head 2 in hexagonal shape, which is integrally connected to a cylindrical, having a bore endpiece 3. The bore is provided with an internal thread 4 and on the cylindrical outer periphery of the extension piece 3, an external thread 5 is attached. The bore having the internal thread 4 passes through the screw head 2. The screw nut element 1 is preassembled on the push rod 9 for the purpose of simplest possible mounting.

Der Figur 3 ist eine schematische Skizze des Anschlusselements 6 zu entnehmen. Das Anschlusselement 6 besteht aus einem geraden Teil, der über einen gekrümmten Bereich mit einem abgewinkelten Teil einstückig verbunden ist. Der abgewinkelte Teil des Anschlusselements 6 ist mit einem einen sechskantförmigen Kopf aufweisenden Gewindestück 7 verschweißt, welches ein Innengewinde 8 aufweist. Eine Kontur des Innengewindes 8 ist deckungsgleich auf eine Öffnung des abgewinkelten Teils angebracht. Hierdurch kann das Schrauben-Mutterelement 1 durch die Öffnung mit dem Gewindestück 7 verschraubt werden. Statt des angeschweißten Gewindestücks 7 kann aber auch ein am Anschlusselement angeformtes Gewinde, das mit dem Schrauben-Mutterelement 1 verschraubt wird, vorgesehen sein. An dem geraden Teil des Anschlusselements 6 ist der Ansatz 12 angeformt, welcher über die Gelenkverbindung an das Bypassventil befestigt wird.Of the FIG. 3 is a schematic sketch of the connection element 6 can be seen. The connecting element 6 consists of a straight part, which is integrally connected via a curved portion with an angled portion. The angled part of the connecting element 6 is welded to a hexagonal head having threaded part 7, which has an internal thread 8. A contour of the internal thread 8 is congruently mounted on an opening of the angled part. In this way, the screw-nut element 1 can be screwed through the opening with the threaded part 7. Instead of the welded threaded piece 7 but can also be an integrally formed on the connecting element thread, which is bolted to the screw nut element 1, may be provided. At the straight part of the connecting element 6, the projection 12 is formed, which is attached via the hinge connection to the bypass valve.

In der Figur 4 ist die Befestigung der Schubstange 9 mit dem Anschlusselement 6 mittels des Schrauben-Mutterelements 1 gezeigt. Die Schubstange 9 weist erfindungsgemäß ein Außengewinde 10 auf, das in Eingriff mit dem Innengewinde 4 des Schrauben-Mutterelements 1 steht. Das Außengewinde 5 des Schrauben-Mutterelements 1 ist mit dem Innengewinde 8 des Gewindestücks 7 verschraubt. Das Innengewinde 4 und das Außengewinde 5 des Schrauben-Mutterelements 1 verlaufen gleichsinnig und weisen hier die gleiche Steigung auf, wodurch eine Montage des Anschlusselements 6 mit der Schubstange 9 mittels des Schrauben-Mutterelements 1 einfach erfolgen kann. Beim Zusammenbau des Abgasturboladers wird für die Verbindung der Schubstange 9 mit dem Anschlusselement 6 das Bypassventil in eine geschlossene Position gebracht und der mit der Schubstange 9 verbundene Aktuator wird ebenfalls in einer der geschlossenen Position des Bypassventils entsprechende Endposition gefahren. Die Schubstange 9 und das Anschlusselement 6 bleiben in ihren daraus resultierenden Positionen stehen, während das auf der Schubstange 9 vormontierte Schrauben-Mutterelement 1 mittels eines externen Werkzeugs auf dem Außengewinde 10 der Schubstange 9 gedreht wird und dadurch in Richtung Anschlusselement 6 bewegt wird. So bewegt sich das Schrauben-Mutterelement auf das Gewindestück 7 des Anschlusselements 6 zu und wird mit seinem Außengewinde 5 mit dem Innengewinde 8 des Gewindestückes 7 in Eingriff gebracht. Ein Toleranzausgleich in Längsrichtung der Schubstanges 9 erfolgt in dem Sinne, dass die Schubstange 9 dabei mehr oder weniger durch das Gewindestück 7 und das Schrauben-Mutterelement 1 hindurch ragt. Die Verbindung ist somit variabel einstellbar.In the FIG. 4 the attachment of the push rod 9 with the connection element 6 by means of the screw nut element 1 is shown. The push rod 9 according to the invention has an external thread 10 which is in engagement with the internal thread 4 of the screw-nut element 1. The external thread 5 of the screw-nut element 1 is screwed to the internal thread 8 of the threaded part 7. The internal thread 4 and the external thread 5 of the screw nut element 1 extend in the same direction and here have the same pitch, whereby a mounting of the connecting element 6 with the push rod 9 by means of the screw-nut element 1 can be done easily. When assembling the exhaust gas turbocharger for the connection of the push rod 9 with the connection element 6, the bypass valve is brought into a closed position and the actuator connected to the push rod 9 is also moved in a closed position of the bypass valve corresponding end position. The push rod 9 and the connecting element 6 remain in their resulting positions, while the preassembled on the push rod 9 screw nut element 1 is rotated by means of an external tool on the external thread 10 of the push rod 9 and is thereby moved in the direction of connecting element 6. Thus, the screw nut element moves toward the threaded part 7 of the connecting element 6 and is brought with its external thread 5 with the internal thread 8 of the threaded part 7 into engagement. A tolerance compensation in the longitudinal direction of the push rod 9 takes place in the sense that the push rod 9 protrudes more or less through the threaded part 7 and the screw-nut element 1 therethrough. The connection is thus variably adjustable.

Im gezeigten Ausführungsbeispiel ist der genannte Aktuator ein elektrischer Aktuator. Ein derartiger elektrischer Aktuator bietet im Vergleich zu einem pneumatischen Aktuator eine höhere Stellgeschwindigkeit, eine höhere Stellgenauigkeit und höhere Stellkräfte. Falls ein pneumatischer Aktuator vorgesehen ist, können auch unterschiedliche Steigungen für das Innengewinde 4 und das Außengewinde 5 verwendet werden. Durch die unterschiedlichen Steigungen der Gewinde verschiebt sich bei der Montage die Verbindung zwischen dem Anschlusselement 6 und der Schubstange 9. Diese unterschiedliche Position kann durch eine Rückstellung einer sich im Aktuator befindenden Feder kompensiert werden und bei der Montage wird die Feder des Aktuators somit vorgespannt. Letzteres ist bei dem elektrischen Aktuator nicht möglich. Bei der Verwendung des elektrischen Aktuators ist es deshalb wichtig, dass das Innengewinde 4 und das Außengewinde 5 die gleiche Steigung besitzen.In the embodiment shown, said actuator is an electrical actuator. Such an electric actuator offers in comparison to a pneumatic actuator, a higher actuating speed, a higher positioning accuracy and higher actuating forces. If a pneumatic actuator is provided, different pitches for the internal thread 4 and the external thread 5 can be used. Due to the different pitches of the thread, the connection between the connecting element 6 and the push rod 9 shifts during assembly. This different position can be compensated by resetting a spring located in the actuator, and during assembly the spring of the actuator is thus prestressed. The latter is not possible with the electric actuator. When using the electric actuator, it is therefore important that the internal thread 4 and the external thread 5 have the same pitch.

In der Figur 5 ist das Schrauben-Mutterelement 1 zusätzlich zu der Ausführungsform in Figur 4 mit einer einen Außensechskant aufweisenden Kontermutter 11 auf dem Außengewinde 10 der Schubstange 9 verspannt. Ist der anhand der Fig. 1 beschriebene Toleranzausgleich erfolgt, dann wird das Schrauben-Mutterelement 1 mit der Kontermutter 11 verspannt. Die Kontermutter 11 verhindert ein Verdrehen des Schrauben-Mutterelements 1 auf der Schubstange 9 während des Betriebs, was einem Verschleiß des Schrauben-Mutterelements 1 vorbeugt. Für eine optimale Montage ist die Kontermutter 11 vor dem Verspannen mit dem Schrauben-Mutterelement 1 auf der Schubstange 9 vormontiert.In the FIG. 5 is the nut-nut member 1 in addition to the embodiment in FIG. 4 with one External hexagon having lock nut 11 clamped on the external thread 10 of the push rod 9. Is the basis of the Fig. 1 described tolerance compensation takes place, then the screw-nut element 1 is clamped to the lock nut 11. The lock nut 11 prevents rotation of the screw-nut element 1 on the push rod 9 during operation, which prevents wear of the screw-nut element 1. For optimum assembly, the lock nut 11 is pre-mounted on the push rod 9 before bracing with the screw-nut element 1.
